Abstract
The invention discloses transverse stretching equipment used for producing a thin film. The transverse stretching equipment comprises a clip closing control device, a double-faced movable chain clip, a continuous guide rail, a pre-heating region, a stretching region, a heating setting region, a separation region, a cooling region and a clip opening control device, wherein the pre-heating region, the stretching region, the heating setting region, the separation region and the cooling region are sequentially and commonly composed of 16 regions. The transverse stretching equipment has very low lubrication requirements and utilizes the complete continuous guide rail; a constant-temperature drying oven has energy-saving and efficient effects; the maintenance is simple; and gas supplied by the cooling region is cooled by a heat exchanger, and the disadvantage that the environment air cooling capability is not enough is avoided.
Description
Technical field
The present invention relates to thin film processing techniques field, particularly relate to a kind of transverse stretching equipment for film production.
Background technology
Synthetic paper utilizes chemical raw material to be made as olefines adds some additives again, there is quality softness, stretching resistance be strong, water-resistance is high, fast light cold-hot corrosion non-environmental-pollution, the good permeability again of chemical substance can be resisted, be widely used for the printing of the senior art work, map, picture album, high-grade books and periodicals etc.In current domestic production equipment used, there are the following problems or defect: very flexible for transverse stretching equipment; Cause film stretching uneven by " bowing effect "; With ambient wind cooling, cause cooling capacity deficiency, temperature unstable; Chain rail cooling device produces condensation, causes rupture of membranes.
Summary of the invention
The object of the present invention is to provide a kind of transverse stretching equipment for film production, high speed; Safeguard simple; Cooling zone air feed is cooled by heat exchanger, avoids ambient wind cooling capacity not enough.
To achieve these goals, the present invention adopts following technical scheme:
A kind of transverse stretching equipment for film production, include and close folder control device, two-sided activity chain folder, strand guide, preheating zone, drawing zone, heating setting area, cut off district, cooling zone and drive folder control device, described preheating zone, drawing zone, heating setting area, partition district and cooling zone are 16 districts' compositions successively altogether, a described district of district to six is preheating zone, seven described districts of district to ten are drawing zone, 11 described districts of district to ten three are heating setting area, 14th described district are for cutting off district, and 15 described districts of district to ten six are cooling zone; 14th described district are for cutting off district, and all the other districts are equipped with strand guide; Described two-sided activity chain folder membrane inlet place presss from both sides control device around contacting with closing, preheating zone is entered with width such as Inlet film, described two-sided activity chain folder enters drawing zone and is in the shape of the letter V and opens, described two-sided activity chain folder enters heating setting area and extends to cut off district and cooling zone to go out the final width parallel of drawing zone, and described two-sided activity chain is clipped in film exit with opening and presss from both sides control device around contacting.
Preferably, constant temperature oven is provided with, precise control of temperature bottom described preheating zone, drawing zone and heating setting area.
Preferably, described drawing zone Nei ten district is provided with rupture of membranes checkout gear.
Preferably, described cooling zone is provided with heat exchanger, and described heat exchanger is made up of air blower and air exhauster, circulation heat-shift.
Described two-sided activity chain folder controls by closing folder control device, clamps and passes the film of coming from last process longitudinal stretching equipment, run along strand guide, simultaneously cross directional stretch film; Constant temperature oven below film, for film preheating, stretching, sizing provide temperature conditions; When two-sided activity chain folder moves to end, by opening after folder control device opens, start next circulation; Film, after sizing, through cooling system fast but, completes cross directional stretch.
Beneficial effect of the present invention:
1, there is the draw ratio of altitude maneuver in each district;
2, high-speed duplex activity chain folder;
3, complete strand guide;
4, constant temperature oven efficient energy-saving;
5, safeguard simply;
6, cooling zone air feed is cooled by heat exchanger, avoids ambient wind cooling capacity not enough.
